Physical modelLing of aluminum melt degassing in low-pressure die casting conditions

Abstract

This paper deals with approximate physical modelling of aluminum melt degassing, performed under lowpressure die casting conditions of aluminum castings. The modelling took place on an aquatic physical model on a 1:1 scale to the operating conditions, constructed in the laboratories of ITB in ČB. Tested parameters were defined based on operating conditions (rotation speed and inert gas flow). Various combinations of these parameters created 20 tested variants, including the current set of parameters used in operating conditions. The effects of the tested parameters were determined using the results of measurement. Increasing the rotation speed and the inert gas flow accelerates gas removal from the model liquid. It will be possible to further use this knowledge in refining technology optimization in the low-pressure aluminum die casting.
